It is beautiful. I've read reviews about the lens being sharp, and also having noticeable barrel distortion in the side / corners, which may or not be important.
It's true that if the cell is dead you have a non-working camera. However, I have several old cameras with selenium cells that work perfectly (an early Canonet, almost contemporary of the Z-10, among those).
This one has program exposure. Open the back of the camera; if exposure / aperture changes when pointing to a light source and to a dark subject, then there is a good chance that the camera works - do a test film and you'll know for sure.
Let us know the results. I'm eyeing a Zorki-11 (same camera without the RF) offered locally....
